A polished script takes numerous drafts and revisions based on constructive feedback from one's writer peers, mentors, and trusted advisers. A pilot episode used to be intended as the prototype for future episodes in terms of format, tone, style, POV, pacing, etc. Today’s TV landscape defies formula, and subsequent episodes can be innovative and/or anomalous to avoid a formulaic, predictive pattern. Without commercials and timeslots, the run time has greater leeway and transcends the format and formulas of legacy television. There is no longer an absolute industry standard regarding the requisite number of episodes per season. Smaller orders tend to be based on budget, size and scope of the series, and availability of TV and movie stars.
